Overview
The ZF 2093.310.064 SPUR GEAR is a precision-engineered OEM component designed for the auxiliary drive and power take-off (PTO) gear train within ZF WG100, WG130, and WG131 transmissions. This gear transfers rotational force from the input shaft to the differential assembly, ensuring smooth torque distribution under heavy loads. As an OEM genuine part (SKU: 2093.310.064), it meets exact factory tolerances for minimal backlash and long service life. This spur gear works in concert with the 5838109012: DIFFERENTIAL to maintain consistent power flow in demanding industrial applications.
Symptoms of Failure
- Whining or grinding noise during gear engagement: A worn 2093.310.064 spur gear produces a distinct high-pitched whine or metallic grinding sound when the transmission is under load, especially during low-speed maneuvers.
- Intermittent gear slipping under heavy torque: As the gear teeth wear unevenly, operators may experience sudden loss of drive power or a “jumping” sensation when accelerating, indicating the gear is failing to maintain positive engagement.
- Metal particles in transmission fluid: Advanced wear of this spur gear sheds fine metallic debris into the oil, visible during routine fluid changes as a glittering or dark contamination in the sump.
- Vibration through the gearshift lever: Excessive play in the gear mesh causes noticeable vibration transmitted through the driveline, often accompanied by a chattering sound at idle.

Compatibility
This spur gear is factory-specified for the following ZF transmission models: WG100, WG130, and WG131. It is also compatible with select variants of the WG180 and WG200 series when used in auxiliary drive configurations. For proper installation, this gear must be paired with the 0750117075: TAPER ROLLER BEARING to support axial loads, and the 2093209023: DIFFERENTIAL for final drive integration. The gear housing must be sealed using the 5838300626: DIFFERENTIAL HOUSING to prevent contamination.

Frequently Asked Questions
Q: Can the ZF 2093.310.064 spur gear be used in a WG180 transmission?
A: Yes, this gear is compatible with WG180 models when used in the auxiliary drive position, though you should verify the tooth count matches your existing PTO configuration.
Q: What is the recommended torque specification for the retaining nut on this gear?
A: The factory specification for the shaft retaining nut is 120 Nm (88 ft-lbs) when used with a new 0750117075: TAPER ROLLER BEARING. Always replace the lock washer during installation.
Q: How can I identify a counterfeit 2093.310.064 gear?
A: Genuine ZF parts have a laser-etched part number on the gear face and a uniform case-hardened surface. Counterfeit gears often show inconsistent tooth spacing or a rough finish on the bore.
